Abstract (en)
[origin: EP0436848A2] Electrical impedance matching for through plane connections or vias (20-44) in a multiplane laminated wiring structure is provided by arranging the vias in patterns conforming to a standard characteristic impedance configuration. The pattern may be a five wire configuration with four vias surrounding the fifth and repeated over the area of the plane.
